It becomes increasingly important because the aerodynamic heating and pressure loads raises so greatly that the performance of the flight and the basic structure are going to be largely affected. In the present paper we performed a numerical model of the problem and analyzed using a commercial Computational Fluid dynamics software, and compared the results with the published data. The key element that we have considered is the double wedge problem and studied the characteristics of the aerodynamics using CFD. The conditions of type III and IV interactions are studied. Our analysis successfully characterized the shock wave interactions. Almost very similar conclusions were made by the published results. There has been a zone of the shockwave interaction and the intersection of this zone has been shared with the intersection of second shockwave due to the second wedge. The slip lines are not observed as the inconsistency.
